Draw a schematic diagram of a circuit consisting of a battery of four 2 V cells, a 5 ohm resistor,  an 8 ohm resistor and a 12 ohm resistor and a plug key all connected in series.

34 A piece of wire is redrawn by pulling it until its length is doubled. Compare the new resistance with the original value? 35 A copper wire has a diameter of 0.5 mm and resistivity of 1.6 ohm cm. How much of this wire would be required to make a 10 ohm coil? 37 Redraw the circuit of problem 6, putting in an ammeter to measure the current through the resistors and a voltmeter to measure the voltage across the 12 ohm resistor. What would be the readings in the ammeter and the voltmeter. 38 Two lamps, one rated 100 W at 220 V, and the other 60 W at 220 V, are connected in parallel to a 220 V supply. What current is drawn from the supply line?
